액상화 가능성 평가를 위한 비파괴 지반조사 방법

Abstract

The liquefaction potential has been widely evaluated by the cyclic stress approach that characterizes earthquake loading with a maximum acceleration and liquefaction resistance frequently with soil strength indices from in-situ tests. This study presents various geotechnical site investigation methods, with a focus on non-invasive methods including seismic reflection, refraction tests and multi-channel analysis of surface waves (MASW), to evaluate the possibility of liquefaction occurrence.
